论文摘要
我们提出了一个确定性但完全被动的方案，将量子态从频率编码的光子转移到由纳米量波导介导的量子点的自旋。我们通过研究所有相关实验缺陷对国家转移保真度的影响来评估国家转移的质量。我们表明，对于实验现实的参数，可以实现超过95％的转移保真度。我们的工作为确定性固态量子网络奠定了基础，该网络量身定制了频率编码的光子量子。
We propose a deterministic yet fully passive scheme to transfer the quantum state from a frequency-encoded photon to the spin of a quantum-dot mediated by a nanophotonic waveguide. We assess the quality of the state transfer by studying the effects of all relevant experimental imperfections on the state-transfer fidelity. We show that a transfer fidelity exceeding 95% is achievable for experimentally realistic parameters. Our work sets the stage for deterministic solid-state quantum networks tailored to frequency-encoded photonic qubits.
